Consider all problems below

Question 1.1) The main issue in the above mentioned network is 1. The issue in transferring large sized files across the network. 2. Physically it is difficult to add computers to the network, because the ceiling is at too high, so installing cable for the new addition to the network is bit difficult. Question 1.2) is it a peer-peer or client server technology. The technology used here is client server technology, it has a centralized control in the network. Question 1.3) The changes in need in the equipment It is better to use a switch in the network to achieve the centralized control, that using a Ethernet Hub. Because switches will have it own memory with all the hosts in the network, so it will avoid the broadcasting effort before starting the transfer of data. It will communicate precisely with the intend receiver over the network. Question 2) Below are the reasons if a computer in the network is not getting the internet. 1. Basic thing was the cable might not plugged well to the computer. 2. Gateway of the internet was not properly configured. 3. Ethernet drivers are not updated to current version. Question 3.1): Type of cable used. Since the network was defined in star topology it is better to go with "Twisted Palr Fiber" cable. Question 4): Network Address: It is a unique identification for a host that was connected to any kind of network. Host Address: It is the physical address of a computer, popularly called as the mac address. It comes with a range under the network. Subnet Mask: It is a 32 bit identification of a host in the network, used to identify the IP address by doing the AND operation bitwise on the netmask. Name one Network service: Helps to achieve client-server technology across all the computers, provides easy way to communicate host to host.Determine the general solution of the given differential equation that is valid in any interval not including the singular point. + 5 Xy + 37 =0 V = (1X 1-3 + COX -1 V = X -5 + COX -1 V = (1X 3 + COX -5 3 V = X + (2X -1 V = CX -3Question 16 2.5 pts The results of a study conducted by Dr. Burns indicated that the correlation between children's aggressive behavior and the number of friends they had was -.80. This correlation coefcient indicates that Q) The less aggressive the child is, the fewer friends a child has. 0 The more aggressive the child is, the fewer friends the child has. 0 A child's aggressive behavior and number of friends are not related. 0 The more aggressive the child is, the more friends the child has. Question 8 (2.3 from text): Figure 2 shows a l-DOF mass damper system. Displacement x is measured 'om an equilibrium position where the damper is at the \"neutral\" position. External force fa(t) is applied directly to mass m. a) Derive the mathematical model (equations of motion) of the mechanical system with position X as the dynamic variable. b] Derive the mathematical model (equations of motion) with velocity v(t) : bit) as the dynamic variable.
